Definitions

  • the invention also relates to a multichannel headphone with at least one sound transducer per headset according to the preamble of claim 1.
  • the invention also relates to a multichannel headphone with a single per headphone capsule arranged substantially in its center sound transducer according to the preamble of claim 7.
  • the invention relates to a multi-channel headphones with a single Sound transducer per headphone capsule, which has a special arrangement according to the preamble of claim 9 in favor of a substantially horizontally located front hearing event.
  • the invention relates to a multi-channel headphones with a plurality of acentrically arranged transducers per headphone according to the preamble of claim 10.
  • the Hörereignislage horizontally-front can be significantly improved by the fact that the radiation of the transducer in each headphone capsule is controlled by a targeted partial steaming or by varying degrees attenuating its radiating surface, for example, the dividing line from an acoustically damped radiating surface to a no or weaker damped radiating surface in the viewing direction of the user preferably partially rising (see characterizing features of claim 11). Due to the inventive measures mentioned in claim 11, therefore, the problem is solved, the Hörereignislage horizontal to improve the front.
  • the above-obtained findings have been abstracted to the effect that the acoustic shadowing effects with respect to the ear canal used for multichannel reproduction (more than two channels) can advantageously be used, in which a plurality of sound transducers per headphone capsule of the multichannel headphone are used (preamble of claim 12).
  • reference numeral 1 denotes the outer ear relief of the left ear of a headphone user
  • the ear-facing partition wall of the left earphone capsule 2a of a stereo small headphone resting on the outer ear 1 is circular and has an outer diameter of about 4 cm.
  • a circular cylindrical sound transducer 3 is arranged, which in a manner not shown from a centrally mounted in the transducer housing bass mid-tone diaphragm and a concentric trained high-tone membrane, which is located approximately at the level of the auditory canal entry point 3 of the ear.
  • a part of the emission surface of the sound transducer 3, namely an upper surface 6 is covered with an acoustically damping material, while the other, the underlying surface 4 is uncovered.
  • the lower partial surface 4 may be covered with an acoustically less strongly attenuating material than the upper partial surface 6.
  • the upper and the lower partial surfaces 6 and 5 adjoin one another via a dividing line 7, which extends in a straight line except for a curved central region 5 and extends in the direction of view of the headphone user, rising from left to right in FIG.
  • the curved dividing line region 5 serves not to cover a part of the high-tone diaphragm of the sound transducer 3 by the acoustically damped partial surface 6, that is to say in FIG. to release.
  • the damped partial surface 6 is arranged such that it faces a part of the outer ear 1 above the auditory canal entry point 3, while the underlying part of the outer ear 1 is irradiated freely by the transducer.
  • an outer ear near / free field Beschallungssituation is obtained, which initializes the outer ear 1 as a directional filter for a binaural Vorneortung of auditory events and consequently the missing in conventional KleinMehrkanalkopf bioern direction filter information of the sensory perception, which has the consequence that the at unrealistic top-to-bottom localization of auditory events is replaced by an essentially pre-location of auditory events corresponding to natural hearing without headphones not partially covered sound transducer.
  • the attenuated sound converter sub-area 6 occupies less than 50% of the total sound transducer radiating area (this is the lower radiating area 4 plus the upper radiating area 6).
  • sloping forward dividing line 7 between the two partial surfaces 4 and 6 results in a distribution of the outer ear sonication, which allows the above-mentioned sensory perception in favor of a Vorneortung of auditory events.
  • Fig. 2 shows schematically in a similar representation as Fig. 1, the arrangement of a left earphone capsule of a four-channel headphone relative to the outer ear 1 of a headset user.
  • the earphone capsule of which only a circular web grid 10 is shown, which serves to hold the transducer, circumaural, in other words has a larger outer diameter than the supraaural headphone capsule 2a of Fig. 1.
  • the center of the Steg grille 10 or the headphone capsule, not shown, is arranged substantially in the region of the auditory canal access point 3.
  • the structure of the web lattice 10 in detail is not of interest for the present invention. It is only essential that the web grating 10 is intended for receiving a (first) sound transducer 11, which may be formed similar to the sound transducer in Fig. 1, i. with a large low-mid-tone diaphragm 12 and a small high-frequency diaphragm 13 concentric with it and for recording a second sound transducer 20.
  • a (first) sound transducer 11 which may be formed similar to the sound transducer in Fig. 1, i. with a large low-mid-tone diaphragm 12 and a small high-frequency diaphragm 13 concentric with it and for recording a second sound transducer 20.
  • the radiating surface of the first sound transducer 11 is subdivided in a similar manner as in FIG. 1 into two partial surfaces, of which an upper partial surface 17a is covered with an acoustically damping material, while the lower partial surface 17b is preferably uncovered.
  • the acoustically damped subarea 17a exclusively covers part of the mid-valley diaphragm 12 and completely leaves the tweeter diaphragm 13 free.
  • the dividing line 18 between the two partial surfaces 16 and 17 extends over the tweeter membrane 13 in a straight line and in the viewing direction, in the direction of the arrow 14, relatively steeply rising at an angle of> 45 °. This surprisingly achieves that the Hörereignislage horizontally front, which is achieved by the special arrangement of the first transducer 11 at the bottom, optimized.
  • the second transducer 20 is shown with double-dashed lines, which is also arranged in the web grid 10 and has the same structure as the transducer 11.
  • the second transducer 20 is disposed substantially diametrically opposite to the first transducer 11 and has a small distance therefrom, such that it adjoins the auditory canal entry point 3 with its outer edge.
  • the radiating surface of the second sound transducer 20 is not partially covered with acoustically damping material, but completely open.
  • the second sound transducer 20 is used for example for level-reduced reproduction of effect signals when using the four-channel headphone in connection with, for example, a DOLBY SURROUND system.
  • the radiating surface of the second sound transducer 20 can also be partially covered, as will be explained below with reference to FIG. 3 for a multi-sound transducer multichannel headphones to improve the traceability of fictitious sound sources.
  • Fig. 3 shows a modification of the embodiment of Fig. 2 with an additional third sound transducer 30.
  • the same elements as in Fig. 2 are designated by the same reference numerals.
  • the arrangement of the second sound transducer 20 in FIG. 3 differs from the arrangement of the sound transducer 20 in FIG. 2 in that in FIG. 3 the sound transducer 20, starting from the center of the web lattice 10, is likewise displaced upwards, predominantly towards the rear.
  • the sound radiating surface of the sound transducer 20 in Fig. 3 is partially covered and thus has an acoustically more heavily damped sub-surface 22 and an acoustically unattenuated sub-surface 21, and the parting line 23 between the two sub-surfaces 21 and 22 is substantially perpendicular, i. parallel to the direction indicated by the arrow 15 (and thus perpendicular to the viewing direction, which is indicated by the arrow 14).
  • the dividing line 23 may also fall horizontally or rearwardly, opposite to the viewing direction.
  • the third sound transducer 30 is disposed almost entirely in a left upper quadrant of the grating 10, and thus upwardly displaced out of the center of the grating 10 with a horizontal shift amount and a predominantly vertical shift amount.
  • the arrangement of the transducer 30 thus corresponds approximately to the mirrored at the horizontal radius 34 of the web 10 arrangement of the front lower transducer 11, but slightly offset relative to the transducer 30 to the rear in the lower left quadrant of the web grid 10 is arranged.
  • the second is Sound transducer 20 predominantly in the upper right quadrant and to a lesser extent in the lower right quadrant.
  • the sound transducer 30 also has an acoustically more heavily damped subarea 32 and an acoustically unattenuated subarea 31, and the parting line 33 between the subareas 31 and 32 extends in the direction of view (arrow 14) sloping at an angle which, with opposite signs, corresponds to the angle of the rising parting line 18 of the transducer 11 corresponds.
  • the first sound transducer 11 is provided with the stereo or front signal, the second sound transducer 20 with a rear effect surround signal and the third sound transducer 30 with a front, e.g.
  • the vertical sound events playing surround effect signal sent to achieve a spatial sound reproduction similar to a corresponding number of speakers.
  • Essential to the arrangement of the sound transducer of Fig. 3 is that the acoustic shading or attenuation of the three sound transducers 11, 20 and 23 are aligned towards optimizing the Ortium to the center of the grating 10 toward or to the auditory entrance.
  • the partition wall 2b is provided, which isolates the inner volume of the earphone capsule 2a from the outer ear 1 and has a recess for the sound transducer 3.
  • a similar partition may be provided in the embodiments of FIGS. 2 and 3. The purpose of this partition is that no or only a certain proportion of sound reflections is reflected from the outer ear and the subsequent head portion of a headphone user in the inner volume of the headphone capsule at located on the outer ear headphone capsule. This ensures that the sound transducer 3 and the plurality of transducers 11, 20 and optionally 30 act as point sound sources. For this reason, the partition wall, for example, partition 2 in Fig.
